                          ISS RECOMMENDS A VOTE ON THE
                    WHITE PROXY CARD FOR THE BOARD'S NOMINEES
                    -----

Dear Fellow Stockholder:

     Institutional  Shareholder Services, Inc., widely recognized as the leading
independent  proxy  advisory  firm in the nation has  recommended  a vote on the
WHITE proxy card FOR the Board's nominees,  Marat Santini,  John Gilgun and Paul
Bulman rather than for PL Capital's nominees.

     o    ISS RECOGNIZED THE QUALIFICATIONS OF OUR NOMINEES:

     "[I]t is essential that the company have board members that  understand the
     community in which they are serving."

     O    ISS RECOGNIZED OUR SUPERIOR PERFORMANCE:

     "A major issue raised by the dissidents is the Company's ability to survive
     in a competitive  landscape.  However,  the Company's  overall  performance
     especially over the last year seems to refute these claims."

     O    ISS RECOGNIZED YOUR BOARD'S LEADERSHIP:

     "Despite an economic  downturn over the last two years,  shareholders  have
     not  suffered  but  have  in  fact  thrived  under  the   incumbent   board
     leadership."

     Your Board and  Management  are  extremely  pleased  that ISS has given its
support to our  nominees.  ISS  listened  to both sides and  concluded  that its
institutional  investor  clients  should  vote for the  Board's  nominees.  ISS'
recommendation  should be considered by any stockholder looking for the judgment
of a knowledgeable, neutral party to guide their vote.

     Please vote for the Board's  three  nominees on the WHITE proxy card today!
DO NOT RETURN PL CAPITAL'S  GREEN PROXY CARD.  USE ONLY THE BOARD'S  WHITE PROXY
   ---
CARD! A "WITHHOLD  AUTHORITY" vote on the PL Capital Group's Green proxy card is
not a vote for the Board's nominees. If you voted on a Green proxy card BUT WISH
TO SUPPORT YOUR  COMPANY'S  NOMINEES,  please  sign,  date and mail the enclosed
WHITE proxy card in the postage-paid envelope provided as soon as possible.

                                              Sincerely,

                                              /s/ John D. Doherty

                                              John D. Doherty


                             YOUR VOTE IS IMPORTANT

1.   The Board of Directors  urges you to DISCARD the GREEN proxy card  recently
     sent to you by the PL Capital Group. A "WITHHOLD  AUTHORITY" vote on the PL
     Capital Group's Green proxy card is not a vote for the Board's nominees. To
     vote FOR your Company's nominees you MUST execute a WHITE proxy card.
2.   If you  voted on a Green  proxy  card BUT WISH TO  SUPPORT  YOUR  COMPANY'S
     NOMINEES,  please sign,  date and mail the enclosed WHITE proxy card in the
     postage-paid envelope provided as soon as possible.
3.   Remember - ONLY YOUR LATEST DATED PROXY WILL  DETERMINE HOW YOUR SHARES ARE
     TO BE VOTED AT THE MEETING.
4.   If any of your  shares  are  held in the  name of a bank,  broker  or other
     nominee,  please contact the party  responsible for your account and direct
     them to vote your  shares for your  Company's  nominees  on the WHITE proxy
     card.
5.   For assistance in voting your shares,  or for further  information,  please
     contact our proxy solicitor:
